Firebase observeSingleEvent stays in memory

Question

My app uses firebase\'s observeSingleEventOfType quite a fair bit and I came to realise that my app\'s memory increase over time. I have commented out all my code except a test

Answer 1

I think this way it will help in xcode too. I have done in my android application.

DatabaseReference ref = FirebaseDatabase.getInstance().getReference("BLAH_BLAH_STRING");

            // Attach a listener to read the data at our posts reference
            ref.addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    // Do Some Stuff
                    ref.removeEventListener(this);
                    ref = null;

                }

                @Override
                public void onCancelled(DatabaseError databaseError) {
                }
            });

Or in iOS , I guess they have different methods to be used.

removeAllObservers and removeObserverWithHandle:

Please try with the given two methods above.
